If it is an airline agent, they will have a rebate policy with the airline. For example, which airline returns a few points, you can use 3+Z value, in which three points are basic points and z value is promotion points. After the agent sells a ticket, the airline's rebate price is multiplied by (3+z) points, which is the agent's agency fee.
If it is an airline, it goes without saying that your own plane will cost money. The more you sell, the better, and their tickets will be sold directly. .
